[Fetal Escobar syndrome--a case report]
Abstract:
The Escobar variant of multiple pterygium syndrome (MPS) is a rare, autosomal recessive disorder which may lead to many serious or even lethal fetal abnormalities. MPS is characterized by pterygia, arthrogryposis (joint contractures), and intrauterine growth restriction (IUGR). In the case described below, increased fetal nuchal translucency was the first abnormality diagnosed already in the first trimester of pregnancy. Other symptoms of the disease were found during the second trimester of pregnancy using ultrasonography examination. Also, genetic amniocentesis revealed no genetic disorders and the Escobar syndrome was diagnosed post mortem. Parental and maternal genetic examinations were performed and allowed for early prenatal diagnostics in the next pregnancy resulting in the birth of a healthy newborn.
Insights
Escobar variant of multiple pterygium syndrome (MPS) is a rare genetic disorder causing severe fetal abnormalities. Postmortem diagnosis in one case led to successful prenatal diagnosis and a healthy birth in a subsequent pregnancy.
Area of Science:
- Medical Genetics
- Prenatal Diagnosis
- Fetal Abnormalities
Background:
- Multiple Pterygium Syndrome (MPS), particularly the Escobar variant, is a rare autosomal recessive disorder.
- MPS is associated with significant fetal abnormalities including pterygia, arthrogryposis, and intrauterine growth restriction (IUGR).
Observation:
- Increased fetal nuchal translucency was detected in the first trimester.
- Ultrasonography in the second trimester revealed additional symptoms consistent with MPS.
- Genetic amniocentesis initially showed no chromosomal abnormalities, leading to a postmortem diagnosis of Escobar syndrome.
Findings:
- The case highlights the diagnostic challenges of Escobar syndrome, often identified postmortem.
- Subsequent parental and maternal genetic examinations were crucial for accurate diagnosis.
- These genetic analyses enabled effective early prenatal diagnostics in a subsequent pregnancy.
Implications:
- Successful prenatal diagnosis in a subsequent pregnancy resulted in the birth of a healthy infant.
- This underscores the importance of genetic testing for rare fetal conditions.
- Early prenatal diagnosis can significantly improve outcomes for families affected by Escobar syndrome.
